Hai all, I'm using JBoss 4.2.2GA version. IDE used is oracle jdeveloper for enterprise java applications based on ejb2.Database used is Mysql. I have created ear from the IDE oracle jdeveloper .Copied the ear to Jboss deploy directory and manually made jboss-cmp-jdbc.xml and added it along with ejb-jar.xml and deployed successfully. My problem is I cudn't deploy my ear directly to jboss from jdeveloper. The error appearing is com.mysql.jdbc.exceptions.MySQLSyntaxErrorException: Unknown column 't0_Opnewregistration.regNo' in 'field list'. Opnewregistration is one of the ejbs used and regNo is fieldname. Once i add jboss-cmp-jdbc.xml, deployment has no problem.But i want to deploy the ear directly from the IDE jdeveloper without any manual configurations Please help me to solve this issue View the original post : http://www.jboss.org/index.html?module=bb&op=viewtopic&p=4214406#...
